specification.

This invention relates to a centrifugal cream separator of that class wherein the whole milk is run into a rapidly revolving bowl and the separated milk. and cream are separate outlets under the influence of centrifugal force.

The im n-oveinents are directed to the application of .a high speed rotating means direct to the body of the separator bowl so that the intervention ,of multiplying mechanism is dispensed with, also to the manner of yielding by mounting the separator bowl adjacent to its center of gravity, on the head of the pivotpin on which it rotates, so asto afford the bowl an opportunity for adjusting itself during rotation.

The invention also comprises features in the construction of the bowl itself by which the entering milk is comp'elledto take up at once the rotatory movement of the vessel.

1 There are also certain subsidiary novel fea- 'tures in the construction of the bowl which renders the interior more readily accessible for cleaning.

The invention is particularly described in the following specification, reference being made to the drawings by which it is accompanied, in which:

Figure l is. a vertical section through the separator bowl and its attached and connected parts, Fig; 2, a cross section on the line A A, Fig; 3, a cross section on the line B B, and Figs. 4 and 5, details to an enlarged scale in section and plan of the adj ustable cream outlet from the bowl'..

In these drawings 2 represents the head of the column on which the separator is mounted and which sustains it at a convenient height from the floor, 9 being a casing, inclosing the bowl and its motor, which casing is removably socketed water tight upon the head of the column 2 and supports thecream and skim milk receiving vessels 18 and 19.

The separator bowl is formed or two parts I 5 and 6, detachable for convenience in cleaning The inner part 5 comprises a"hollow cylindrical, stem portion which is ocnically enlarged toward the lower end and from the lower part of which enlargt lent downwardly projects an impact h me l0 by which a direct. rotatory movement is unparted to the bowl by jets of a fluid under pressure directed on the vanes of the turbine from noizzles 11 on diametrically opposite sides. The outer part6 of the separator-bowl is j ointec' l at 7 onto a conical seat of the inner part imifiediately above the turbine. This outer portion 6 converges toward the upper end to a'contracted neck upon the upper end of which bears a nut 8 threaded Mm th neck of the inner portion 5 W115, limit 56- cures the outer and inner portion together to form the bowl.

Arourd the inside of the enlarged portion of the outer part 6 of the bowl are a number of inwardly projecting vanes 16 which taper slightly from the lower to the upper end. These vanes form a most important part of my invention and by their use I am enabled to dispense with the conical laminae commonly used in separator bowls. These vanes may be integral with or secured to the body of the bowl and may be radial or in: clined slightly from the radial line as drawn. The separator bowl thus formed is .pivotally mounted on the spherical upper end of pin 4 stepped into a bearing in the upper end of a support 3 projectin upward axially from the head 2 of the co umn, the.

bearing of the pin 4 being provided in the support- 3 with a ball race to reduce the friction.

Removably mounted on the cylindrical portion of the bowl inner member 5 is a sleeve 13 to the lowerend of which just above the lateral apertures 12 from the hollow of the stem is secured an outwardly coned baflle 1a which seats upon the bottom of thebowl adjacent to the conical seat 7. Thisbafile 14 is provided around its lower edge with a series of apertures 15 for deliv cry of the whole milk to the lower part of the bowl.

In the seat of the nut 8 on the upper end of the outer ortion 6 of the bowl'is cut a passage 20 t irough which the skim milk occupying the outer part of the bowl during rotation, passes into the receiving vessel 19 for delivery through the spout 22, and in the nut is an aperture 23 at a smaller radial distance for delivery of the cream which passes into its receiving vessel 18 for delivcry-through the spout 25.

Figs. and show in enlarged detail how I this cream exit may be adjusted in its radial distance to enable the quality of thecream to'be regulated. This end is attained by .forining theaperture 23 as a groove in'the.

outside of a bushing-24: rotatable in a drilled aperture of the nut 8. The bushing may thus be rotated and'the radial distance of the aperture 23 varied within the limit of. the diameter of the bushing. The bushing may be secured in any position of adjustment by means of a set screw.

In use the whole milk fromfthe vessel is delivered in the usual way through a stopcock 31 and float check 32 to the central passage 17 of the separator bowl. From there it passes through the lateral apertures 12 and .rotating means to the separator bowl, the

manner of mounting the bowl adjacent to its center of gravity on the head of the pin on which it rotates so that the ldowl is free to adjust itself. to its true center of gyration; and the general simplicity of construction by which the parts of the bowl are rendered accessible for cleaning. There is also the means by which the grade of cream as delivered from the bowl may be varied.

Having now particularly described my invention and the manner of its operation, I hereby declare that what I claim a s nen and desire to be protected in by Letters Patent is;

1. In a centrifugal milk separator, a column support, a bearing mounted on said column support, a separating bowl having a pin to enter said bearing, said separating bowl comprising an inner membbrconsisting of a tubular stem or neck having a conical enlargement at its lower end," and provided with an annular coni'foriii seat on said lower end, said bowl including an outer member havmg an enlarged. body; provided with an opening in its bottom having a coniform seat to engage the conii'orm seat of the inner member, said outer memberhaving a restricted neck into which the reduced neck of the inner. member projects, the neck of said outer member being spaced irom the neck of said inner member, said inner member neck being l dnger than said otter member neck and terminating at its unperend in a threaded portion, a nut on said threaded portion to bear against said outer neck and retain said outer and inner members with the conical seats in engagement with one "secured to said baffle to support the same,
